Crystallization of the C-terminal head domain of the fibre protein from a siadenovirus, turkey adenovirus 3

Abstract

Turkey adenovirus 3 belongs to the genus Siadenovirus. Its predicted fibre protein consists of an N-terminal virus-attachment domain, a central shaft domain and a head domain at the C-terminus. The head domain has little sequence identity to known adenovirus fibre head structures. Crystals of the fibre head domain consisting of amino acids 304-454 with an N-terminal purification tag were produced. Crystals of native and selenomethionine-derivatized protein belonged to space group I23 (unit-cell parameter 99 Å). They diffracted synchrotron radiation to 2.0 and 2.14 Å resolution, respectively, and are expected to contain one monomer in the asymmetric unit. © 2013 International Union of Crystallography All rights reserved.
